Heat a skillet over medium-high. Toss tofu/tempeh with half the olive oil and half the spice mix. Sear until golden and a bit crusty, about 4–6 minutes per side.
Add the chickpeas and sliced vegetables. Drizzle with the remaining oil and spice. Sauté until everything is tender-crisp and nicely caramelized, 5–7 minutes.
Make the garlic-tahini sauce: whisk tahini with lemon juice, minced garlic, water, and a pinch of salt until creamy. It should thin enough to drizzle—adjust with water as needed.
Warm your bread briefly to soften (a quick flip in the pan works). Slice and lay it out flat for assembly.
Spread a generous line of sauce, pile on the veggie mix, sprinkle herbs, and add any extras you love. Fold or roll into a wrap and cut in half.
